"The 700-day android engineering bridge officer is now available as a synthetic female or male.

Also added science and tactical versions of the android Bridge Officers, both male and female.
The female versions of the androids have the same skills.
You may still only have one android per captain.
If you discharge an android officer, you may claim a replacement at no cost.
Go to the Bridge Officer Requisitions at Earth Spacedock/Qo'noS to claim an android officer."
